May I ask why do you listen to those folks? Do not listen to anyone. Do your own analysis.
Do you really think they'll do 16nm, and waste all the money and development they did on 20nm? If that's true, and you think Intel will be at a significant disadvantage, perhaps its time to start selling intc stock.
If not, then you think they have a chance, and even grow, you'll keep it in. Really that simple.
